There has been growing interest in the design and development of tunable light emissive materials that have potential applications in lighting and displays. In this paper, we have incorporated the aggregation induced emission (AIE) with excited-state intramolecular proton transfer (ESIPT) process into one molecular skeleton for generation of color-tunable emitting materials. As expected, the high air/photo-stability of TPE-based asymmetric Schiff-base chromophores 1–2 displayed clear AIE characteristics and significant advantages in terms of tunable emission containing blue, warm white, as well as orange-red in solution. More importantly, all compounds 1–4 display brilliant colors by adjusting the intensity of blue and red emission in a mixture with a polymer in the solid state. This innovative research would provide a new, efficient channel for the discovery of well-organized full color emitting organic materials.

基于四苯乙烯的颜色可调AIE-ESIPT发色团
人们对可调谐发光材料的设计和开发越来越感兴趣,该材料在照明和显示器中具有潜在的应用。在本文中,我们已经将具有激发态分子内质子转移(ESIPT)过程的聚集诱导发射(AIE)整合到一个分子骨架中,以生成颜色可调发射材料。如所预期的,高的空气/光稳定性基TPE不对称席夫碱生色团1 - 2显示在含有蓝色,暖白,以及橙红色溶液中的可调谐发射的术语明确AIE特性和显著优点。更重要的是,所有的化合物1 - 4通过调节固态聚合物与混合物的蓝光和红光的发射强度,可以显示鲜艳的色彩。这项创新研究将为发现组织良好的全色发射有机材料提供一个新的有效渠道。
